CHAIR-ARM.

Specification of LettersPatent.v i

Application filed June 20,. 1911. Serial No.A 634,297., f

To all ywhom t may concern.' Be it known that we, JAMES BARKER, AL- FRED BAKKER, and JOSEPH P.. BAKKER, citizens of the United States, residing in Phila- 5 delphia, county of Philadephia, State of Pennsylvania, have invented` certain Improvenients in Chair-Arms, of which the following is a specification.

One object of this invention is-.to improve l0 the construction of chair arms, particularly those used on barbers and dentists chairs..r

It is desirable in chairs which are daily occupied by a number of different people, such for instance as barbers chairs, to make the parts as sanitary as possible. This object we attain by making the body portion of the arm of vitreous material such as china, glass or other equivalent material, so that it can be quickly and readily cleansed.

A. further object of the invention is to constructthe arm so that the vitreous material will be properly supported and will not be liable to crack or break, due to uneven expansion, or due to the clamping of the glass upon a rigid base.

A still further object of the invention is to make the body of the arm in such a manner that the supporting medium will be hidden from view.

In the accompanying drawings Figure l, is a plan view of a chair arm, illustratingour improvement; Fig. 2 is a longitudinal sectional view on the line 2 2, Fig. l;

Fig. 3, is a transverse sectional view on the line Fig. 2; Fig. 4, is a transverse sectional view on the line lf- 4 Fig. 2; Fig. 5, is a detached perspective view of the metallic base section upon which the arm is mounted; Fig. 6, is a perspective view of the vitreous body portion; Fig. 7, is a perspective view of the intervening coupling section; Fig. 8, is a view showing the filling block and washer, and Fig. 9, is a sectional view illustrating a modification of the invention.

A is the metallic base having perforated lugs a at each end, which are attached to the moving parts of the chair, as it will be understood that this particular form of base is used in connection with a barbers chair in which the back and foot rests are movable.

B is a glass body portion, in the present instance, and C is the intervening coupling section. A Thefglassxbody section has a-deep:y

flange and is hollow, as clearlyV shown in F ig., 2. Theupper fsurfaceof the glass' Patented'Ag. 20,1912.v

chair, lalthoughfthe shape ofl the larm may be modifiedfwithout"departing from rthe essential features of the invention.

Thewcoupling section C is preferably made of wood in a comparatively rough state and issecuredto the base A by screws c. The glass body is secured to the wooden coupling section C by screws e. The heads of these screws are mounted in metallic washers e', which rest in cavities b in the glass body section B and mounted between the underside of these washers and the glass are washers f, of flexible material, preferably of leather, and mounted between the body sect-ion B and the coupling section C, at the rear of the handle, is a washer g of yielding material, while at the forward end is a block E through which the screw e passes and between the upper end of this block and the glass' section is a washer g and the couplingv block is so proportioned that the flange b does not rest upon the metallic base A, but is clear of it, so that there is no direct contact between the metallic base and the glass body. Some suitable cement, as indicated at 71, is preferably inserted in the space between the glass'and the flange a of' the base A so as to close the crevices and to make the handle absolutely sanitary.

In order to hide the wooden coupling sections C, we preferably make the body portion of opaque glass or china, and if it is desirable to highly ornament the handle we may make t-he body portion of clear glass and coat its inner surface with an opaque bronze or paint so that the bronze not only hides the coupling section, but also improves the appearance of the glass arm.

In Fig. 9, we have illustrated a modification of our invention in which the long wooden lling section C is dispensed with and two spools C', C are used and the screws e2 extend through the spools and are tapped into the metal of the base portion of the handle. Leather or other yielding material is placed between the spool and the glass section of the handle and between the handle and the screws, and cement is placed between the flange on the base portion and the lower edge of the glass handle7 so as to prevent the accumulation of foreign matter and thus make the handle sanitary.

By the above construction the parts can be readily assembled without danger of breaking or cracking the vitreous material and the arm can be kept absolutely clean. Furthermore, the body portion being` made of glass, or like material can be molded into any shape desired so as to conform to the hand and arm of the occupant of the chair.

We claim:

The combination in a chair arm, of a metallic base; a vitreous body portion mounted above the base; with a coupling section of wood located between the vitreous body section and the base and inclosed within the body section; independent means for securing the Wooden coupling section to the base; independent means for securing the vitreous body section to the coupling section; and means for preventing direct con tact between the vitreous body section and the base of the coupling section.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
